October 9, 20204 yr comment_607550 Leaks from the fitting? Can use Teflon tape, or permatex thread sealer and see if that helps. Link to comment https://www.classiczcars.com/forums/topic/64535-radiator/#findComment-607550 Share on other sites More sharing options...

Drilled a hole in it so it worked like the plastic ones. It's surprising how few options there are for those plugs, and all of the options are poor quality.

It's surprising how few options there are for those plugs, and all of the options are poor quality. I did exactly what Zed Head did on my O'Reilly radiator too but I didn't drill a hole for draining. I have to pull the lower hose off to get the fluid out. I also used Teflon tape as Heyitsrama suggest.
